摘要：

为满足实时显示高速数字图像的需求，分析了Camera Link 接口技术和VGA（Video Graphics Array）接口协议的标准。根据VGA接口具有多种显示模式，设计了以FPGA（Field Programmable Gate Array）为核心处理器的数字图像采集显示方案。FPGA通过Camera Link 接口采集图像数据，并对图像进行缓存处理，对FPGA构造VGA 接口的时序信号和控制视频D/A进行数字量的模拟化。实验证明，该系统实现了图像的实时显示。人机交互和采集后的图像可以进行长距离传输。

Abstract:

In order to display digital image in realtime at high speed,the Camera Link interface and VGA（Video Graphics Array）interface protocol standard is analyzed, according to the VGA interface which has a variety of display mode,adigital image acquisition and display program is designed by the FPGA（Field Programmable Gate Array）as the core processor, and the FPGA acquired image data through the Camera Link interface, then the image is cached and processed, as well as FPGA structure timing signal of VGA interface and control the video D/A digital simulation, finally realize real-time display of images,simple control and transmit to long distance after prosessed image.

Key words: digital image, field programmable gate array(FPGA), video graphics array（VGA）, camera link
